HD 80606b was discovered in 2001 by a Swiss planet-hunting team led by Dominique Naef of the Geneva Observatory, Switzerland. It's a gas giant planet - much like Jupiter in our own solar system but about four times more massive. The exosolar planet HD 80606b has a highly eccentric (e=0.93) and tight (a=0.47 AU) orbit. We study how it might arrive at such an orbit and how it has avoided being tidally circularized until now. The presence of a stellar companion to the host star suggests the possibility that the Kozai mechanism and tidal dissipation combined to draw the planet inward well after it formed: Kozai.

HD 80606b is a gas giant planet in an eccentric orbit around its star. Every 111 days, the planet passes within 2.8 million miles of the star's surface. During the close approach of Nov. 20, 2007, NASA's Spitzer Space Telescope observed the system for 30 hours. Scientists modeled the response of the planet's upper atmosphere to the extreme heating. The animation based on their simulations begins 4.4 days after closest approach, when the hot hemisphere has rotated into view. Play store download for mac. A massive storm has formed in response to the pulse of heat delivered during the planet's close swing past its star. Nikon software download for mac. Successive frames, spaced every 12 hours, show the hot spot rotating out of view. The Spitzer observations represent the first time astronomers have detected weather changes in real time on a planet outside our solar system. Canon mf4880dw driver download for mac.
